COMBINED SASH AND DOOR CHECK.

To all whom it may concern:

Be it known that I, GEORGE F. EHEMANN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in a Combined Sash and DoorCheck, of which the following is a specification.

This invention relates to a combination door and sash-lock; and has forits object to provide a device of this character that is simple inconstruction, easy of manipulation and may be put on and taken ofi withfacility.

Figure 1 is an elevation showing the device attached to a door. Fig. 2is an elevation showing the same attached to a window sash. Fig. 3 is aplan. Fig. a is a view of the vertical part. Fig. 5 is a view inperspective, showing the locking member detached. Fig. (3 is a. detailof construction. Fig. 7 is a modification.

The device consists of two parts, an anglebracket A and a locking arm B.The bracket consists of the horizontal plate 8 and the vertical plate 9,comprising an integral structure, as best shown in Figs. 5 and 7. Inpractical use, the plate 8 passes under the bottom of the door, theplate 9, extending upward against the inner side, as shown in Fig. 1.The bracket is temporarily secured in place by a pointed pin 10, fixedin the bottom plate 8 and which will be of such a length as to readilypermit of the plate being slipped in under the door and the pin forcedup into the same. When the device is to be more securely or permanentlyattached, the plate 9 may be provided with a number of apertures 11 forthe insertion of fastening screws.

The plate 9 is provided on the upper end with a tubular hinge-roll 12,and a slot 13 extending downward therefrom and vanishing in a hole let.The hinge-roll is divided in the center, the adjacent ends being beveledas at 15, to provide bearing points 16.

The movable locking-arm B will be bent so as to assume the properbracing angle when in its engaged position. This arm has a cross-bar 17formed 011 the upper end thereof which is adapted to have a looseengagement with the hinge-roll 12 and provide for the hinge movement ofthe arm Specification of Letters Patent.

when it is made to assume either of its two positions. IVhen the arm Bis raised or lowered, it passes the points 16, which bear against thesurface of the arm close to its junction with the cross-bar and has theeffect of spreading the edges of the slot 13, which return to theirnormal position after the arm passes the center and drops into the freespace on either side and is retained against accidental displacement.

A foot 18, is threaded on the lower end of the arm B and is adapted tobe adjusted endwise in lengthening or shortening the arm, bringing thefoot to a proper bearing on the floor. This foot will ordinarily becomposed of rubber or other suitable material that will not mar orscratch the surface it comes in contact with.

Fig. 1 is a modification in that it shows a bifurcated locking-arm 19having clawends 20 which are adapted to be embedded in the floor whenthe device is used temporarily, as a lock when the door is closed. Thedevice will hold a door open at any point between a closed and wide openposition, and when the door is closed, it provides an additional lock.The device is easily manipulated with the thumb and finger and when notrequired for use may be conveniently thrown up against the door, out ofthe way and leaving the door free.

Fig. 2 shows the application of the de vice to a window. In this casethe plate 9 is inserted between the meeting sash rails and fastened tothe inner sash-rail 21. The foot 18, when in its engaged position, bearsagainst the side rail 22 of the upper sash. This will permit of eithersash being opened and locked at any desired point or both at the sametime.

Having thus described my invention, what I claim is 1. In a device ofthe character described, the combination with a T-shaped shank, of afloor engaging head carried thereby, and a hinge member carried by thedoor and in which said T-shaped shank is pivotally mounted, said hingemember comprising a vertical slotted body portion, roll portions formedupon said body portion, and cam members formed upon said roll portionswhich engage said shank and hold said shank at either of its limits ofmovement.

2. In a device of the character described, the combination with a floorengaging inember, of a hinge member with which said floor engagingmember is pivotally engaged said hinge member comprising a verticalslotted body portion and a rolled portion, said rolled portion havingcam surfaces formed thereon which engage the floor engaging member tohold the same at either of its limits of movement.

I11 testimony whereof I affix my signature in presence of two Witnesses.
